COSRX Oil-Free Lotion with Birch Sap — 3.38 fl oz Lightweight Hydrating Moisturizer for Oily & Acne-Prone Skin

COSRX Oil Free Lotion with Birch Sap is a lightweight, non-greasy daily moisturizer that hydrates oily and combination skin using 70% birch (willow bark) water for fast absorption and a refreshed finish.

This oil-free lotion is formulated to hydrate without heaviness, making it suitable for people who want moisture without added shine. It combines high-concentration birch sap with a clean formulation that avoids parabens, sulfates, phthalates, and animal testing. The texture is designed to absorb quickly so you can layer actives, sunscreen, or makeup without pilling.

How does this lotion fit into a morning routine?

Apply after cleansing and any lightweight serums to seal in hydration without leaving a greasy film. Its fast-absorbing formula allows sunscreen and makeup to sit evenly on top. Because it’s oil-free, it helps control shine while maintaining comfortable skin hydration throughout the day.

• Use 1–2 pumps over serum; pat until absorbed.
• Compatible with chemical sunscreens and mineral SPF.
• Ideal for layering under makeup to reduce midday shine.

Can this help acne-prone or irritated skin?

The lotion is formulated for blemish-prone and reactive skin types by focusing on lightweight hydration and a minimal-irritant ingredient list. While not an active acne treatment, the birch sap base soothes and supports barrier recovery, which can reduce redness and sensitivity from dryness or topical actives.

• 70% birch (willow bark) water for gentle hydration support.
• Hypoallergenic, dermatologist-tested formulation.
• Free from parabens, sulfates, phthalates, and animal testing.

How does the texture and absorption perform?

The lotion has a light, milky texture that sinks into skin quickly without leaving residue. It provides a hydrated, silky finish — not an oily sheen — so skin feels refreshed and smooth. This makes it practical for both daytime and nighttime use.

• Non-greasy, fast-penetrating consistency.
• Suitable for use after water-based serums and before creams, if extra moisture is needed.
• Leaves a soft, touchable surface that helps makeup adhere evenly.

Is this product safe for sensitive skin and free from common irritants?

COSRX designed this lotion to be gentle and widely tolerable: it’s hypoallergenic and dermatologist tested. The formula intentionally omits common irritants and harsh preservatives to reduce the chance of flare-ups. Still, patch testing new products is recommended for very reactive skin.

• Dermatologist tested and hypoallergenic labeling.
• Formulation excludes parabens, sulfates, and phthalates.
• Animal testing-free and suited for cautious skin types.

Who is this for: COSRX Oil Free Lotion with Birch Sap is aimed at people with oily, combination, or acne-prone skin who want reliable daily hydration without added oil or weight. It’s a good fit for those who use active treatments (like exfoliants or retinoids) and need a gentle, fast-absorbing moisturizer to maintain skin comfort. If you prefer lightweight textures, need a makeup-friendly base, or look for cleaner ingredient lists, this lotion is designed to slot into your routine with minimal fuss.
